Fig 1. Electromechanical embolectomy device in its corkscrew form.
A, The SMP-nitinol corkscrew microactuator is mounted at the distal end of a microcatheter. The copper leads (and nitinol wire) extend from the proximal end of the microcatheter for connection to the power supply. A close-up of the microactuator showing the radiopaque gold markers (arrows) is seen in the inset. Scale divisions are in millimeters.
B, Microscope image of the microactuator showing the copper-wound nitinol wire encapsulated by the SMP. The diameter of the microactuator is 0.3 mm (0.012 inches). Scale bar = 1 mm.
